To all; whom ii may concern.

Be in; known that l, FRANK Eooonsnnsiq, citizen of tlic Unilcd SEREUS oil Amer lea, and resident of Snringlield, inllic county of Hamptlen and State of Massachusetts, have invented certain new and useful linproveinents in Drilling Attachments for Various Classes of Machines, 01 which the following is a fall, clear, and exact description.

cs ccially available for small Work and a cquabcly meeting lhe'rcquirsznenls in the execution of such Work in shops where there may be an absence in the equipment, for instance, of multiple spindle, and radial, drilling I The present invention consisls in an attacllment comprising a body, a plurality of drill spindles-adjosiably carried by the body, a shalt engaged with, but rotatable independently of, the body and adapted to' be chucked. iutlie latlie, drill prcss or other ma chine, gearing and connections between the sald shaft and spindles for securing rotaions of the latter for the rotation of the former, and it'urthermore,as is especially essential and important,-an extension or handle provided lo the body by means of which fine latter may be manually held against being rotated While theclrilling av;- tachment is being operated. A

The invention furthermore consists in certain specific combination or arrangement of parts, and the particular construction of some of the parts, which constitute the drilling attachment, all substantially as herein after fully described and setforth in the claim.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings,-tl1c attachment is shown as including a stock or body comprising a Fig. 5 is a plan View showhollow circular or cup shaped gear casing A constructed with a clctacliably fastened annular cap plate A The gear casing has, in the design shown, three radially extended integral lugs a rigidly connected With which are-depending posts 7) supporting at their lower encls and suitablybelow and scpaieled from the hollow gear casing a ring"- shaped support 13 for a plnralily of bars (3 which are adjustable on lire said supporling ing in plane at right angles to the axis of the stock or body; and these bars carry al itliclr inner-ends rotatable but endwise immovable,

The drill receiving sockets, one of which is represented by clotted lines at (5'? in Fig. l, are of considerable extent Within the lengths of the drillspincllcs so that allowance is thereby ali'orded for a long range of adjustment of the drills, the shanks of which may be inserted more or less far as desired in such sockets.
